WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
High Pressure Natural Circulation Steam Boiler. The NUK-HP® is a high-pressure natural circulation boiler operating by the gravity circulation principle. Therefore circulating pumps are not required to operate the NUK-HP®. Boiler water is used as the heat carrier. The water is evaporated in this boiler within a hermetically sealed circuit.
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …
Oct 07, 2015· It is compactly designed to provide steam supply for deodorization and physical refining of oils and fats efficiently. The Aalborg High Pressure Natural Circulation (HPNC) steam boiler from Alfa Laval is a high performance boiler developed to comply with the rigorous specifications of the food and vegetable oil industry.
Feb 02, 2016· The high-pressure boilers are widely used for power generation in thermal power plants. Example: Lamont boiler, Benson boiler, loeffler boiler, Babcock and Wilcox boiler Features of High pressure Boilers 1. Forced circulation of water 2. Large number of small diameter tubes 3. Higher steam pressure and temperature 4.
Aug 10, 2019· The circulation of water through a boiler may be natural or Forced type. In all modern high-pressure boiler plants, water circulation is with the help of Pump i.e. by means of Forced Circulation. Type of tubing and drums: To avoid large resistance to the flow of water, these boilers have a parallel set of an arrangement of tubes.
Under the subcritical pressure, the natural circulation boiler with the flue gas parameter of 16.6~18.2 MPa and the working pressure of the drum reaches 18.6~20.6 MPa, and the natural circulation still has sufficient water circulation driving force to achieve safe and reliable operation.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
High Pressure Boiler | Water Tube Boiler High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell.During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.
natural circulation boilers The natural circulation boiler – type iNook is a High Pressure Steam generator of vertical design especially developed for closed circuits. It is installed directly below the steam consumer (the condenser) connected to it and not capable of being shut off.
The NUK® High-Pressure Steam Generator is a closed-looped (hermetically sealed) system that produces steam for high-temperature applications. Therefore, this steam generator is able to produce non-toxic process heat while offering the same advantages of a conventional hot oil system .
Natural circulation high pressure steam boilers type HPB Steam output 300 – 8,000 kg/h This type of boiler is a variant of the water tube steam boiler and is very well suited to the generation of steam with higher pressures.
